Application filed November 17 1908. Serial No. 463,028.

in at Cochranton, in the count of Craw ford and State of Pennsylvania,have invented certain new and useful Improvements in Adding and ListingMachines, of which the following is a specification.

The object of the present invention is to prevent the obtaining of wrongresults in the operation of adding and listing machines such as mightcome about through manipulation of the controlling keys and operation ofthe machine with the printing platen out of position to receive animprint. It is obvious that if a machine of this character has produceda list of items or accumulator, and then with the platen out of printingposition an amount is set up on the keyboarc and the machine operated,the total" exhibited by or contained in the accnmulatonwill be greaterthan the actual total of the printed list of amounts. Furthermore, ifafter printing a list of amounts and adding the same the total key ofthe machine is depressed and the machine operated with the platen out ofprinting posi-- tion, the accumulator may be cleared or left at ner'owhile no record of the total is preserved. 4

The present invention provides means whereby neither addition of amountsin the counter or accumulator nor the printing-of amounts can take placewhile the platen 'is out of printing position and also means wherebythe'total key'or keys cannot be. operated so long as the platen remainsout of printing position and in the latter connection provision ismadewhereby the platen cannot be moved out of printing position with thetotal key operated.

With these and incidental objects in View the invention consists incertain novel features of construction and combinations of parts theessential elements whereof are recited in the appended claims and apreferred form of embodiment of which is illustrated in the accompanyingdrawings and described'in detail hereinafter.

Of said drawings, Figure 1 represents a left side elevation-partially insection-of part of an adding machine of the wellknown Burroughs type,with the present invention applied thereto; and'Fig. 2 is asectionalized right side elevation of the same machine.

The invention is preferably shown as adapted to said Burroughs type ofmachine, though it is not to be understood as limited in this regard butmay be adapted to other types of adding and listing machines. It will beunnecessary to enter into a detailed description of the, Burroughsmachine, since its general construction and mode of operation is wellunderstood,-the machine being in extensive use and illustrated anddescribed in various prior patents, see, e. 2, William S. BurroughsPatents Nos. 504:,963 and 505,078, issued September 12, 1893. However,some of the familiar parts of such machine will be specificallymentioned hereinafter as they have more especially to do with theoperations of the present invention.

Referring first to Fig. 1, reference numeral 291 designates the usualdepressible amount keys which-operate upon bell cranks 217, the'latterengaging slides or slide strips 214 which, when first pushed rearwardlyby depression of amount keys, are temporarily held back by pivoteddetents 228. These keys, as usual, measure the excursions of racks 910which operate the adding pinions 916. The accumulator, composed of saidpinions and suitably inscribed wheels, is controlled in the usual mannerso that in add ing operations the racks 91 turn said pinions and wheelsforward when said re cks are restored to normal position.

The numeral 265 designates the usual total key which through thecustomary connections reverses the order of engagement and disengagementbetween the racks and the pinions, so as to cause the latter to beturned backward to zero position as the racks descend.

The numeral 265 designates the subtotal key which operates upon the sameconnec tions as the total key but with a modified ef-' fect, so that thepinions, after being turned to zero, will be again advanced to thetotal.

In Fig. 1 the numeral 9.09 designates the left side piece of a restoringbail mounted upon across-shaft 207, normally retracted by a spring 208and operating as usual to preserve roller platen 17'. Said frame rocksfrom a position in which said platen may receive imprints from the type618 to apositionwhere the work can be examined when the-I platen isremoved from printing position,

as indicated by dotted lines in Fig. 2.

In Fig. 2 the reference numeral 209 designates the right side piece ofthe before-- mentioned ball, which side piece has as usual. a dependingarm carrying a roller 209 co-- operating with a wipe plate 623 in theusual manner to effectan automatic release and restoration of depressedamount keys at the.

conclusion of an adding operation'of the machine. Said 'Wipe plate ispivotally mounted on a three-armed lever 622 impelled in one directionby a spring 688 implied to the wipe plate and rocked in the oppositedirection by the full stroke sector 311. In carrying out the presentinvention in the form of embodiment here shown, there is secured to therock shaft 207 of the aforesaid bail a rearw-ardly projecting arm 10with a roller 11 at its end overlying an arm 12 loose on a cross shaft503. Loosely mounted on the rock shaft 207 is a generally sector-shapedplate 13 having a branch carrying a roller 14 which underlies said arm12. The rearend of the plate 13 is slotted in the arc of a circle toembrace the journal 16 of the usual feed rollers 16 on which the platen17 rests when in printing position. The said plate is normally held byits own weight to a lowered position, such as illustrated in full linesin Fig. 2, leaving the aforesaid bail to vibrate in the usual manner forautomatically releasing and restoring the keys or effecting this resultthrough depression of the usual correction key 265. It will-be obvious,however, that an upward swinging of said plate will cause its roller 14to move, the arm 12 upward and consequently rock the bail forward byreason of the action of said arm 12 upon the roller 11. The throwingback of the platen frame carrying the platen out of printing positionhas the effect of swinging said plate upward and producing theabovedescribed result, which not only releases and restores any depressedamount keys, but also holds the bail forward, preventing depression ofany amountkeys. To this end the said plate 13 has an upwardly andrearwardly curved arm 19 which carries a partly spherical roller 20 inposition to be acted upon by an inclined and beveled strip 21 which issecured to a crossbar 21 of the rock frame 15*. With the said rock frameforward and the platen in printing position, said inclined and beveledstrip lies below and away from said roller 20 as shown in full lines inFig. 2. But when the frame is thrown upward and backward said strip,acting upon said roller, elevates theplate 13 to the dotted lineposition illustrated in Fig. 2, thereby swinging the key .releasing andrestoring bail forward .as also be no depression of amount keys andconse-- quently no adding of amounts upon the counter and no operationoft'hetypes fo amount printing.

The total key 265 as usual surmounts a bell crank lever 227 and thelatter is. connected by a link 146 with a crank arm secured to a shaft146*. The subtotal key is likewise mountedv upon a bell crank lever 227*and through the medium of a link 227 and a stud 227 on the lever 227operates the latter. Thus depression .of either the total or sub totalkey rocks the shaft 146*, as will be obvious from an inspection of Fig.1 of the drawings. Near its right hand end said ,shaft 146*, Fig. 2,carries an arm 23 with a laterally projecting stud 24 at its upper end.A bell crank lever 25 is'mounted under the right hand portion of thekeyboard with one arm projecting forward and its extremity normallystanding just above and to the rear of said stud 24. The other arm ofsaid bell crank extends downward and is pivotally connected to a link226 which extends rearwardly and is pivotally connected to the rightside piece of the key-releasing and restoring bail, said ling beingslotted at an intermediate point for engagement with the correction keylever. It will be seen, therefore, that the rocking of the bail such asproduced by throwing back the platen carrier or frame draws the link 226rearward, bringing the front end of the forwardly extending arm of thebell crank 25 behind the stud 24, thus locking both the total andsubtotal keys against depression. Furthermore, with the roller platen inprinting position depression of the total or subtotal key carries thestud 24 beneath said forwardly extending arm of the bell crank 25 andthus by locking the bail against forward movement prevents the platenfrom being thrown back. It follows that the machine cannot be operatedto take a total or subtotal with the platen out of printing position.

Inasmuch as depression of the total or subtotal key locks thekeyreleasing and restoring bail, means are provided for preventing thespring movement of the lever 622 when either of said keys has beenoperated or otherwise wipe plate 623 would be unable to pass the roller209 when moving in the upward direction and the machine would be put outof commission. To this end there is secured to the shaft 146 an arm 26with a downwardly and rearwardly turned upper end adapted to cooperatewith a stud 27 pro i tthe printing and totaling mechanism as an eeaeiojecting from the forwardly extending arm of the lever 622. Thus wheneither the total or subtotal key is operated the extremity of said arm26 is brought down on top of the said stud 27 and blocks movement of thelever 622 which would otherwise take place under the influence of thespring 688.

The correction key 265 operates in the usual way to rock the bail exceptwhen the subtotal or total key has been depressed, in which case thecorrection key is locked out by reason of the fact that the link 226cannot be thrust rearward. Furthermore, when the correction key has beendepressed neither the subtotal nor the total key can be depressedbecause said link has been thrust rearward and the bell crank 25 broughtdown behind the stud 24. I

It will now be seen that the above described construction is thoroughlycapable of fulfilling the objects primarily stated but at the same timeit is to be understood that the invention is capable of embodimentotherwise than as here shown and described, though I do not claimbroadly the idea of eliminating addition by the throwing back of thepaper carriage.
